[PATCH v2 1/5] dt-bindings: arm: mediatek: mmsys: add mt8195 SoC binding

[jason-jh.lin <jason-jh.lin@mediatek.com>]

1. There are 2 mmsys, namely vdosys0 and vdosys1 in mt8195.
   Each of them is bound to a display pipeline, so add their
   definition in mtk-mmsys documentation with 2 compatibles.

2. Add description for power-domain property.
